Objective To evaluate the significance of combined detection of leptin (LEP),tumor necrosis factor-α (TNF-α),carcino-embryonic antigen (CEA),C-reactive protein (CRP) and interleukin-6 (IL-6) in both serum and pleural effusion in differential diagnosis of tuberculosis and malignant tumor.Methods LEP,TNF-α,CEA,CRP and IL-6 levels in both pleural fluid and serum samples from 95 cases of pleural effusion (including 54 cases of malignant pleural effusion and 41 cases of tuberculous pleural effusion) were detected by immunoturbidimetry and enzyme linked immunosorbent assay (ELISA),respectively.The data with normal distribution and skewed distribution were analyzed by t test and rank sum test,respectively.Results In patients with tuberculosis and malignant tumor,significant difference was observed in serum LEP [(0.42±0.47) ng/ mL vs (1.80±0.91) ng/mL,t=9.666,P=0.0001],TNF-α [(30.88±24.72) pg/mL vs (59.83±30.93) pg/mL,t=4.917,P=0.0001],CEA [(0.22±0.30) ng/mL vs (5.67±3.60) ng/mL,t=ll.074,P=0.0001] and IL-6 [(146.48±54.90) pg/mL vs (20.51±11.62) pg mL,t=-14.449,P 0.0001] levels.Serum CRP levels of patients with tuberculosis and malignant tumor were comparable [(32.78±22.43) mg/mL vs (37.80±16.74) mg/mL,t =1.249,P=0.215].In pleural effusion of the two groups (tuberculous pleural effusion vs malignant pleural effusion),LEP [(0.69±0.65) ng mL vs (4.33±2.16) ng mL,t 11.711,P 0.0001],TNFα [(20.60±17.80) pg/ mL vs (40.40±20.60) pg/mL,t=4.926,P=0.0001],CEA [(0.10±0.17) ng/mL vs (4.02±2.49) ng/ mL,t=11.537,P=0.0001] and IL-6 [(87.80±48.40) pg/mL vs (9.30±5.50) pg/mL,t =-10.333,P=0.0001] levels were significantly different,while CRP levels [(27.34±17.93) mg mL vs (29.60± 13.40) mg mL,t =0.709,P =0.102] were comparable.Conclusion LEP,TNF-α,and CEA levels in both pleural effusion and serum samples from patients with malignant tumor are higher than those with tuberculosis,while IL 6 levels are quite opposite.Combined detection of these parameters can help the differential diagnosis of tuberculous and malignant pleural effusion.

This study was aimed to select the best preparation form of medicinal in camellia cake,based on the optimal antithrombotic agents in oil tea camellia defatted cake to establish the foundation of research.The content of effective index component of the oil tea camellia defatted cake preparation was detected by HPLC-PDA.The quality of medicinal preparation from oil tea camellia defatted cake was characterized based on the content,relative quantity,relative ratio of content,yield rate and antithrombotic effect.The results showed that the effect of antithrombotic of three medicinal preparations from oil tea camellia defatted cake was listed in the following descending order of enrichment,ethanol extract,and water extract.The enrichment was the best preparation form of medicinal in oil tea camellia defatted cake preparation with the highest content of effective index components,the lowest extract rate and the lowest dosage.But it had the best effect of antithrombotic.It was concluded that the significant improvement of efficacy was due to the increase of the content of the components in the preparation and the rationality of the proportion.At the same time,analysis of component quality based on basic composition of drug system through the consideration of effective components of type and quantity,composition and other quality factors can further guide the preparation of drugs.

Objective To explore the efficacy of comprehensive community-based rehabilitation on chronic schizophrenia and assess in the view of health economy. Methods 80 chronic schizophrenic patients accepted comprehensive community-based rehabilitation for 1 year and were followed up for 1 year. Other 80 chronic schizophrenics were as the controls. They were observed with outcome and the cost. Resultsn The social function, compliance, stability rate, burden on family caregiver, satisfaction of living, psychiatric symptoms, hospitalization were all better in the rehabilitation group than in the control group (P<0.01), and the total cost in the 2 years was less, especially that on hospitalization,maintenance treatment, work loss of caregivers, public prevention (P<0.01). Conclusion Comprehensive community-based rehabilitation can improve the outcome of chronic schizophrenics with less cost.

OBJECTIVETo study the inhibitory effect of Acanthopanax giraldii Harms Var. Hispidus Hoo polysaccharides (AGP) on SGC-7901 gastric cancer cells and its possible mechanism.

METHODSCell doubling time analysis, colony forming assay and MTT assay were adopted to study the inhibitory effect and its characteristics. We also analyzed the amount of protein expressed by oncogenes, antioncogenes and cell factors using flow cytometric analysis.

RESULTSAGP inhibited the proliferation of SGC-7901 cells and cell colony forming ability. AGP did not inhibit the viability and function of lymphocytes of peripheral blood in healthy subjects and human embryonic tenocytes, except for the highest dosage of AGP (P < 0.05), which slightly inhibited the viability and function of the two types of normal cells. AGP inhibited the viability and function of SGC-7901 cells, except for the lowest dosages of AGP I and AGP III. There was a dose-effect relationship between the dosage of the AGP and SGC-7901 cells. The effect of the AGP at the molecular level was associated with the low protein expression of the c-myc and bcl-2 genes and the high protein expression of the p53, bax, fas and fas-L genes, as well as the cell factor TGF beta(1). The inhibitory effect of AGP was weaker than that of CDDP, but was stronger than that of Vitamin C.

CONCLUSIONSAcanthopanax giraldii Harms Var. Hispidus Hoo polysaccharides selectively inhibited the proliferation, the colony forming ability, and the viability and function of human gastric cancer cells through the low protein expression of c-myc, bcl-2 and the high protein expression of p53, fas, fas-L and the cell factor TGF beta(1). The different inhibitory characteristics on the normal cells and cancer cells are possibly caused by gene and the cell factor expressions.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common public health problem worldwide. Recent studies have reported that socioeconomic status (SES) is related to the incidence of COPD. This study aimed to investigate the association between SES and COPD among adults in Jiangsu province, China, and to determine the possible direct and indirect effects of SES on the morbidity of COPD. METHODS: A cross-sectional study was conducted among adults aged 40 years and above between May and December of 2015 in Jiangsu province, China. Participants were selected using a multistage sampling approach. COPD, the outcome variable, was diagnosed by physicians based on spirometry, respiratory symptoms, and risk factors. Education, occupation, and monthly family average income (FAI) were used to separately indicate SES as the explanatory variable. Mixed-effects logistic regression models were introduced to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for examining the SES-COPD relationship. A pathway analysis was conducted to further explore the pulmonary function impairment of patients with different SES. RESULTS: The mean age of the 2421 participants was 56.63 ± 9.62 years. The prevalence of COPD was 11.8% (95% CI: 10.5%-13.1%) among the overall sample population. After adjustment for age, gender, residence, outdoor and indoor air pollution, body weight status, cigarette smoking, and potential study area-level clustering effects, educational attainment was negatively associated with COPD prevalence in men; white collars were at lower risk (OR: 0.60, 95% CI: 0.43-0.83) of experiencing COPD than blue collars; compared with those within the lower FAI subgroup, participants in the upper (OR: 0.68, 95% CI: 0.49-0.97) tertiles were less likely to experience COPD. Such negative associations between all these three SES indicators and COPD were significant among men only. Education, FAI, and occupation had direct or indirect effects on pulmonary function including post-bronchodilator forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC), FEV1, FVC, and FEV1 percentage of predicted. Education, FAI, and occupation had indirect effects on pulmonary function indices of all participants mainly through smoking status, indoor air pollution, and outdoor air pollution. We also found that occupation could affect post-bronchodilator FEV1/FVC through body mass index. CONCLUSIONS Education, occupation, and FAI had an adverse relationship with COPD prevalence in Jiangsu province, China. SES has both direct and indirect associations with pulmonary function impairment. SES is of great significance for COPD morbidity. It is important that population-based COPD prevention strategies should be tailored for people with different SES.
